The ground of faith -- God's word

Psalm 138 gives the ground of faith God's word; and now the
godly turns to own it in worship; and when that word reaches the
kings of the earth, they shall turn and praise Jehovah and sing in
His ways. Nor is His truth all. Though so high, He has respect to
the lowly; He revives, protects, and perfects all that concerns the
believing righteous. "His mercy endureth for ever."
